1. Formula of molarity is
a. moles divide by volume
b. moles multiply by volume
c. mass multiply by volume
d. mass divide by volume

Answer 1

Answer:

a. moles divide by volume

Explanation:

Molarity, denoted by symbol M, refers to the molar concentration of a solution. It is calculated using the formula as follows:

Molarity = number of moles of a solute ÷ volume of the solvent

Since, number of moles (n) has the unit: moles and volume (V) has the standard unit: Litres, then the unit for molarity is moles/litre or M.
